Calling Restlet client resource from server resource causes HTTP 404 error

Question

I have a Restlet server application that calls client resource for the purpose of hitting a google endpoint.

When I get to the point in my code:

ClientResource storeRoot = new ClientResource("http://googleendpoint");
  String jsonString = storeRoot.get().getText();

I get the warnings and errors:

Jan 7, 2013 4:33:34 PM org.restlet.engine.component.ClientRouter getNext WARNING: The protocol used by this request is not declared in the list of client connectors. (HTTPS/1.1). In case you are using an instance of the Component class, check its "clients" property. Not Found (404) - The server has not found anything matching the request URI at org.restlet.resource.ClientResource.doError(ClientResource.java:612)

I have googled around and seen that the solution is likely adding the protocol to the endpoint like this:

component.getClients​().add(Protocol.HTTPS​);

The problem is that I am running this as a war file in tomcat. Where do I access this component object to add the protocol?

I have also changed my web.xml to support this protocol like this:

<?xml version="1.0" encoding="UTF-8"?>
 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

Answer 1

After a lot of heartache I determined that solution was the addition of params in the web.xml that Andy stated above and also the addition of the following jars:

org.restlet.ext.net org.restlet.ext.httpclient org.restlet.ext.ssl

Answer 2

Try adding the following to your web.xml, inside the <servlet> element.

<!-- Your application class name -->
<init-param>
    <param-name>org.restlet.application</param-name>
    <param-value>test.MyApplication</param-value>
</init-param>

<!-- List of supported client protocols -->
<init-param>
    <param-name>org.restlet.clients</param-name>
    <param-value>HTTP HTTPS FILE</param-value>
</init-param>
